CVSS: 6.8EPSS: 0%CPEs: 12EXPL: 1CVE-2020-25689 – wildfly-core: memory leak in WildFly host-controller in domain mode while not able to reconnect to domain-controller
https://notcve.org/view.php?id=CVE-2020-25689
A memory leak flaw was found in WildFly in all versions up to 21.0.0.Final, where host-controller tries to reconnect in a loop, generating new connections which are not properly closed while not able to connect to domain-controller. This flaw allows an attacker to cause an Out of memory (OOM) issue, leading to a denial of service. The highest threat from this vulnerability is to system availability. Se encontró una fallo de filtrado de memoria en WildFly en todas las versiones hasta 21.0.0.Final, donde el controlador de host intenta reconectarse en un bucle, generando nuevas conexiones que no son cerradas apropiadamente mientras no es capaz de conectar al controlador de dominio. Este fallo permite a un atacante causar un problema de Falta de Memoria (OOM), conllevando a una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-25689 https://security.netapp.com/advisory/ntap-20201123-0006 https://access.redhat.com/security/cve/CVE-2020-25689 https://bugzilla.redhat.com/show_bug.cgi?id=1893070 • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2020-14299
A flaw was found in JBoss EAP, where the authentication configuration is set-up using a legacy SecurityRealm, to delegate to a legacy PicketBox SecurityDomain, and then reloaded to admin-only mode. This flaw allows an attacker to perform a complete authentication bypass by using an arbitrary user and password. The highest threat to vulnerability is to system availability. Se encontró un fallo en JBoss EAP, donde la configuración de autenticación se configura usando un SecurityRealm heredado, para delegarlo en un SecurityDomain PicketBox heredado, y luego se vuelve a cargar al modo de solo administrador. Este fallo permite a un atacante llevar a cabo una omisión de autenticación completa mediante el uso de un usuario y una contraseña arbitrarios. • https://bugzilla.redhat.com/show_bug.cgi?id=1848533 https://access.redhat.com/security/cve/CVE-2020-14299 • CWE-287: Improper Authentication •
